Military submarines travel underwater in an environment of total darkness with neither windows nor lights. Operating in stealth mode, they cannot use their active sonar systems to ping ahead for underwater hazards such as undersea mountains, drilling rigs or other submarines.
The windows are located in the free flooding area of the sail. When submerged this area floods with water and so the windows would have minimal differential pressure against them. These windows allow the maneuvering party to stay out of the weather while navigating the boat on the surface.
Submarines navigate these challenges using robust engineering and sophisticated materials. The windows, or portholes, are a structurally vulnerable point.

Submarines float on the surface by using ballast tanks full of air. There are valves at the top of the ballast tanks that are opened when it's time for the submarine to submerge. As the air escapes, seawater comes in a the bottom of the tank. It makes the sub heavier, and then it submerges. It takes four people on duty to drive the submarine whethe...
One way a submarine can surface is called blowing to the surface. To do this, high-pressure air is blown into the ballast tanks to replace the seawater. It's the weight of the seawater that is keeping the sub underwater, so displacing it makes the sub rise to the surface. Another way is to drive to the surface. A submarine has planes along its stem...
That's classified. What the Navy can tell you is that their submarines can submerge deeper than 800 feet. But they don't go as deep as the research subs that explore the seafloor.
The Navy's nuclear-powered submarines can stay submerged for long periods of time. Air isn't a problem as their make their own oxygen and keep the air clean. The limits on how long they can stay underwater are food and supplies. Submarines generally stock a 90-day supply of food, so they can spend three months underwater. The diesel-powered submari...
No, Navy submarines don't have windows or portholes so the crew can watch undersea life. Submarines have only periscopes for outside vision, and those are only used close to the surface, a periscope depth (PD). Submariners can look around 360 degrees with the periscope to find other ships and aircraft in the area and to gain information on a target...
Modern periscopes not only have the dashed lines you are familiar with from old movies, but they also have night vision, video and still cameras, magnification and internal antennas.
Navigation is set by the Submarine Navigators and Quartermasters and guided by computers on the ship. They use ocean navigational charts. The ship receives signals from Global Positioning System (GPS) satellites when near enough to the surface to use an antenna. and Quartermastersuse ocean navigational charts They can also use a sextant when on the...
Normally, a submerged submarine will not rock with the motion of the waves on the surface. It is only in the most violent hurricanes and cyclones that wave motion reaches as much as 400 feet below the surface. In these conditions, submarines can take a five to ten-degree roll.
This is classified as well. However, U.S. nuclear-powered submarines can go faster than 23 miles per hour, which is 37 kilometersper hour or 20 knots (nautical miles per hour) underwater.
Surface Tension: The shape of the tear drop hull design allows a submarine to slice cleanly through the ocean when there is water on all sides - as well as house sensitive sonar equipment. But when it is on the surface, it uses energy to generate the bow wave and wake. and then less energy is put into propulsion. Designs for World War II vessels an...

Portholes on submarines are generally made of acrylic plastic. In the case of deep diving submarines, the portholes can be several inches thick. The edge of the acrylic is usually conically tapered such that the external pressure forces the acrylic window against the seat.
Unlike what we see in movies or on themed underwater tourist subs, real working submarines, especially military ones, do not have windows. In this post, we’ll delve into the reasons behind this design choice and how it impacts submarine operations.
